Effect of Tacrolimus on Peripheral Nerve Regeneration in Allograft Transplantation: A Light and Electron Microscopic Study.

Objectives: Peripheral nerve injuries are common in Europe; however, the treatment techniques may lead to disabilities. This study aimed to evaluate the effect of tacrolimus use on the capacity of the epineural sheath graft to improve its regeneration quality in rat sciatic nerves as a treatment option for nerve injuries.

Materials And Methods: In the experimental process, 30 male Sprague Dawley were used as recipients and 10 Wistar rats were used as donors.

Acute dental pain elevates salivary oxytocin in women: a risk factor during pregnancy.

Irreversible pulpitis is an acute, brief, and painful condition. Oxytocin, cortisol, and secretory immunoglobulin A (sIgA) are released by the body in response to pain and emotional stress. The aim of this study was to investigate the expression of salivary cortisol, sIgA, and oxytocin among patients with irreversible pulpitis.

Astaxanthin alleviates oxidative damage in acute pancreatitis via direct antioxidant mechanisms.

Background/aims: Astaxanthin (ATX) is a naturally occurring carotenoid and a potent antioxidant. Various anti-inflammatory effects of ATX have been examined. We aimed to investigate the protective effect of ATX and its mechanism in a cerulein-induced acute pancreatitis rat model.

Encapsulated melatonin in polycaprolactone (PCL) microparticles as a promising graft material.

Electrospraying assures many advantages with taking less time and costing less relatively to the other conventional particle production methods. In this research, we investigated the encapsulation of melatonin (MEL) hormone in polycaprolactone (PCL) microparticles by using electrospraying method. Morphology analysis of the produced particles completed with Scanning Electron Microscopy (SEM).

Melatonin supports alendronate in preserving bone matrix and prevents gastric inflammation in ovariectomized rats.

The anti-catabolic bisphosphonate alendronate is considered as the first-line medical treatment in post-menopausal osteoporosis; but several side effects, including gastric mucosal injury, are associated with its use. The aim was to elucidate whether combined treatment with melatonin plus alendronate would be more advantageous in the maintenance of bone and the prevention of gastric side effects. Under anaesthesia, female Sprague-Dawley rats underwent bilateral ovariectomy (OVX), while control group had sham surgery.
